Abstract

This study was carried to investigate the effect of corn substitution by 50% crude glycerol with or without fibrolytic enzymes in lactating Baladi goats ration on digestibility, nutritive values, rumen liquor and blood parameters and lactation performance. Thirty multiparous lactating Baladi goats after 7 days of parturition were divided into three groups (10 animals each) according to its production then, the experimental groups were randomly assigned to fed one of the following experimental rations, control ration (R1) consists of 60% concentrate feed mixture and 40% Egyptian clover, R2, 50% of corn was substituted with crude glycerol or R3, consists of R2 supplemented with fibrolytic enzymes (ALLZYME™) at level of 6 g/kg DM. Although, inclusion of glycerol alone (R2) or with fibrolytic enzymes (R3) in lactating goat rations decreased nutrients and fiber fractions digestibility and nutritive value as TDN, but they did not significantly (P<0.05) differ with control (R1) in DCP, blood and rumen liquor parameters, milk yield and composition. Addition of fibrolytic enzymes to glycerol ration (R3) increased nutrients digestibility, nutritive values and milk fat content compared with ration containing glycerol alone (R2). It could be concluded that crude glycerol could be used as a source of energy in ruminant rations with fibrolytic enzymes as additive without negative effects on lactating goats' health and performance.
